The emergence of handheld analyzers came from the need to make testing processes more efficient, cost effective and safe in various industries. For example, safety and security; the traditional testing process was costly and time consuming, with hazardous chemicals delivered to a laboratory for analysis and results coming days or weeks after. With handhelds, a more complete picture of a sample is formed in real time since data can be obtained in the field and answers are delivered immediately.
In history, two major events prompted the use of handheld analyzers: the fall of the telecom industry and the rise of Silicon Valley. Engineers working in telecom brought their expertise in optical technology to new industries with batetry like Anritsu MT9081 Battery, Anritsu MT9081D Battery, Anritsu MT9082 Battery, Anritsu 9081D Battery, Anritsu Z0921A Battery, Anritsu MT9083 Battery, Anritsu MT9083B Battery, Anritsu MT9083A8 Battery, Anritsu CMA-4500 Battery, Anritsu CMA-4500 Battery, Tektronix YBT250 Battery, Tektronix TFS3031 Battery. And the growing number of technology startups in Silicon Valley led to the miniaturization of software-based tools and consumer electronics. These facts helped bring handheld technology to more people, places and industries.
The early 2000s gave rise to the demand for handheld RF analyzers. These analyzers were used in the cellular market during large roll outs of base stations, as these stations needed to be installed and commissioned. The goal was to bring them on air within a few months.
The key was IC development and integration that allowed RF test equipment to be created in a handheld portable form-factor. This was accompanied by the development of smaller, yet more powerful, processors and batteries. “Anritsu started developing RF handheld test equipment in the late 1990s, and Keysight Technologies entered this market in 2008, with a 6-lb portable combination network spectrum analyzer called FieldFox,” says Wilkie Yu, Marketing Manager for RF/μW Handheld Analyzers., Keysight Technologies Inc.
In the DC/low-frequency test equipment world, handhelds have been around for years, and it’s rare to find electrical engineers who haven’t used or don’t own a digital multimeter (DMM).
In the world of analytical handheld analyzers, users demand more connectivity, with easier access to more data. “The instrumentation market as a whole is moving to Cloud-based solutions, to providing ‘smart’ tools that can connect to the Web, and many of our instruments already have these capabilities,” says Maura Fitzpatrick, Marketing Director, Portable Analytical Instruments, Thermo Fisher Scientific. The benefit of “smart” tools is they make it easier to download the software and diagnostic information and manage teams spread geographically.
In addition to “smart” tool connection, handheld analyzers now incorporate multiple technologies in one. “This helps limit the amount of equipment field operators need to carry and it’s another example of how the intelligence is built into innovative instruments, making them accessible to experts and novices alike,” says Fitzpatrick. Earlier in 2015, Thermo Fisher Scientific introduced its Thermo Scientific Gemini handheld chemical analyzer. One of the key benefits of the technology is the user can switch between Raman and FTIR spectroscopy. These dual-technology features are only growing in importance to the analytical handheld world.
In the RF and microwave market, Keysight Technologies is seeing the development of new applications and additional functionality. “Emerging satellite programs to deliver global broadband access and the Internet of Things (IoT) are driving the need for lower-cost and multi-function test solutions, from R&D to installation and maintenance,” says Yu. With the proliferation of new applications and wireless devices, there’s also growing demand for interference analysis and spectrum monitoring portable tools.
